On the reflection of magnon bound states

Research output: Contribution to journalArticlepeer-review


We investigate the reflection of two-particle bound states of a free open string in the light-cone AdS 5 ×S 5 string sigma model, for large angular momentum J = J 56 and ending on a D7 brane which wraps the entire AdS 5 and a maximal S 3 ¿ S 5. We use the superspace formalism to analyse fundamental and two-particle bound states in the cases of supersymmetry-preserving and broken-supersymmetry boundaries. We find the boundary S-matrices corresponding to bound states both in the bulk and on the boundary.
